Are the steps you take to create train an adult chi (almost 3 years old) any different than training another kind of dog or a puppy?

I have a comfy mat in there, snacks and water so he's got what he needs and he sleeps a lot anyway. I have the crate with the door opened right now in my room so he can go in if he wants to
